论文摘要
Nagaoka极限中跨核骨环的T -J Hamiltonian已解决。由于存在自旋，能量光谱被量化，其中每个能级对应于自旋链的环状置换状态。当环包含n = 2，3个跨性硬核玻色子时，基态是真正的铁磁。对于所有其他N，它是铁磁和非铁磁性状态的混合物。这种行为与费米子环不同，那里的基态仅在n = 3中是真正的铁磁。有人认为，自旋翻转状态的低躺式兴奋水平本质上支持超流量。还讨论了实验验证这些结果的可能方法。
The t - J Hamiltonian of the spinful hard-core bosonic ring in the Nagaoka limit is solved. The energy spectrum becomes quantized due to presence of spin, where each energy level corresponds to a cyclic permutation state of the spin chains. The ground state is true ferromagnetic when the ring contains N = 2, 3 spinful hard-core bosons; for all other N it is a mixture of the ferromagnetic and non-ferromagnetic states. This behaviour is different from the fermionic ring, where ground state is true ferromagnetic only for N = 3. It is shown that the intrinsic spin generated gauge fields are analogous to the synthetic gauge fields generated by rotation of either the condensate or the confining potential. It is argued that the low lying excited levels of the spin flipped states intrinsically support the superfluidity. Possible ways to experimentally verify these results are also discussed.
